What aspects of infants' prelinguistic communication are most valuable for learning to speak, and why? We test whether early vocalizations and gestures drive the transition to word use because, in addition to indicating motoric readiness, they (a) are early instances of intentional communication and (b) elicit verbal responses from caregivers. In…

Purpose: Behavior and temperament (e.g., emotional reactivity, self-regulation) have been considered relevant to stuttering and its developmental course, but the direction of this relation is still unknown. Knowledge of behavior difficulties and temperament in childhood stuttering can improve screening and intervention. The current study examined…

Purpose: Consonant repetitions within words are a well-attested speech error pattern in children's early speech acquisition. We investigated the role of intervening vowel context in understanding speech forms containing consonant repetitions in early words. Intrasyllabic consonant-vowel (CV) sequences within consonant-vowel-consonant (CVC) and…

Purpose: Parent report was compared to judgments made by a trained researcher to determine the utility of the Vocal Development Landmarks Interview (VDLI) for monitoring development of vocal behaviors in very young children. Method: Parents of 40 typically developing children, ages 6-21 months, provided full-day naturalistic audio recordings of…

It is widely accepted that play and 'free play' in particular, is beneficial to young children's holistic development. However, there is a lack of evidence of the role that the natural environment can have in relation to young children's play. This study examined the elements of 'free play' of children aged 4-5 years within a woodland university…

Gastrointestinal symptoms (GIS) are commonly reported in children with autism spectrum disorder (ASD). This multi-site study evaluated the prevalence of GIS in preschool-aged children with ASD/(n = 672), with other developmental delays (DD)/(n = 938), and children in the general population (POP)/(n = 851). After adjusting for covariates, children…

This study examines the infant-father attachment in infants born preterm (<?1500?g at birth and/or?<?37 weeks gestation) in comparison to full-term infants. The infant-father attachment was assessed using the Strange Situation Procedure at a (corrected) age of 15 months. We found at least half of preterm and full-term infants (50.0% and…

This study examined the course and correlates of the happy victimizer tendency--the expectation that harming others to achieve a goal will result in positive emotional outcomes for the transgressor--from 4 to 6 years of age in a community sample of Canadian children (N = 150; 50% female; Time 1 M[subscript age] = 4.53 years, SD = 0.30; 33%…

This study examined whether childhood interparental conflict moderated the mediational pathway involving adolescent exposure to interparental conflict, their negative emotional reactivity to family conflict, and their psychological problems in a sample of 235 children (M[subscript age] = 6 years). Significant moderated-mediation findings indicated…

Recognizing the inherent attention in examining how educational practices affect our future, there is little known about society's demands related to early childhood education. This paper aims to analyze the current preschool enrolment situation in the Euro-Western world and the demands of society, focusing attention on the characteristics needed…

Neuroscientific advances and child development studies show 0-6 years represents a sensitive period for the development of emotional competence--the ability to identify, understand, express and regulate emotion, all foundational to self-regulation. Research suggests optimum teaching of emotional competence and self-regulation skills from birth is…

In the daily news cycle, national and global debates constantly swirl around issues of justice, equity, and civility, with concerns raging about the core elements needed for individuals, communities, and nations to interact successfully. No doubt, children are impacted by the way these issues play out on the world stage. However, they also learn…

Anger is a central characteristic of negative affect and is relatively stable from infancy onward. Absolute levels of anger typically peak in early childhood and diminish as children become socialized and better able to regulate emotions. From infancy to school age, however, there are also individual differences in rank-order levels of anger. For…

Cognitive development is thought to depend on the refinement and specialization of functional circuits over time, yet little is known about how this process unfolds over the course of childhood. Here we investigated growth trajectories of functional brain circuits and tested an interactive specialization model of neurocognitive development which…

Research examining the effects of subsidized childcare prior to school entry for child development is inconsistent. This population-based study examines the relationship between two poverty levels (extreme poor and working poor) and children's developmental outcomes, as measured by the Early Development Instrument. It also determines the extent to…
